gst-launch-1.0, how to remove title bar

Better Solution: I was using nveglglessink and could not figure out how to remove the title bar, so I stumbled on to nvoverlaysink, it puts up the output without title bar. It bypasses wayland and/or X, Hopes this helps others Terry

As you know that nvoverlaysink bypasses X, you would understand that mirroring with X would not help.

X mirroring mirrors the X display, but nvoverlaysink overlays onto a local display. For mirroring with nvoverlaysink, you would use tee in gstreamer pipeline and have each nvoverlaysink setting its display-id (such as 0,1).
